Yep, it overwrote my bindings but that’s ok

I have the code to implement them already. Really appreciate the help on that one, was driving me crazy

Hi! I'm trying to get two Workers to communicate using RPC, but it's not working when I try to use a named export.

When I try to call

methodX()

methodX()

methodX()

methodX(), I get this error:

The RPC receiver does not implement the method "methodX"

The RPC receiver does not implement the method "methodX"

The RPC receiver does not implement the method "methodX"

The RPC receiver does not implement the method "methodX"

Here's my setup that's NOT working:

In Worker A's config file (wrangler.toml), I have:

compatibility_date = "2024-10-22"
[[env.staging.services]]
binding = "STORAGE_SERVICE"
service = "storage_service"
entrypoint = "StorageService"

compatibility_date = "2024-10-22"
[[env.staging.services]]
binding = "STORAGE_SERVICE"
service = "storage_service"
entrypoint = "StorageService"

compatibility_date = "2024-10-22"
[[env.staging.services]]
binding = "STORAGE_SERVICE"
service = "storage_service"
entrypoint = "StorageService"

compatibility_date = "2024-10-22"
[[env.staging.services]]
binding = "STORAGE_SERVICE"
service = "storage_service"
entrypoint = "StorageService"

And in Worker B, I'm doing:

export class StorageService extends WorkerEntrypoint<Bindings> {
    async methodX() {
        // stuff happens here
    }
}
export default {
    async fetch() {
        return new Response("Hello world");
    }
}

export class StorageService extends WorkerEntrypoint<Bindings> {
    async methodX() {
        // stuff happens here
    }
}
export default {
    async fetch() {
        return new Response("Hello world");
    }
}

export class StorageService extends WorkerEntrypoint<Bindings> {
    async methodX() {
        // stuff happens here
    }
}
export default {
    async fetch() {
        return new Response("Hello world");
    }
}

export class StorageService extends WorkerEntrypoint<Bindings> {
    async methodX() {
        // stuff happens here
    }
}
export default {
    async fetch() {
        return new Response("Hello world");
    }
}

But here's the weird part

if I remove the named entrypoint stuff and just do it like this, it works perfectly:

compatibility_date = "2024-10-22"
[[env.staging.services]]
binding = "STORAGE_SERVICE"
service = "storage_service"

compatibility_date = "2024-10-22"
[[env.staging.services]]
binding = "STORAGE_SERVICE"
service = "storage_service"

compatibility_date = "2024-10-22"
[[env.staging.services]]
binding = "STORAGE_SERVICE"
service = "storage_service"

compatibility_date = "2024-10-22"
[[env.staging.services]]
binding = "STORAGE_SERVICE"
service = "storage_service"

ith Worker B simplified to:

export default class StorageService extends WorkerEntrypoint<Bindings> {
    async methodX() {
        // stuff happens here
    }
}

export default class StorageService extends WorkerEntrypoint<Bindings> {
    async methodX() {
        // stuff happens here
    }
}

export default class StorageService extends WorkerEntrypoint<Bindings> {
    async methodX() {
        // stuff happens here
    }
}

export default class StorageService extends WorkerEntrypoint<Bindings> {
    async methodX() {
        // stuff happens here
    }
}

Any ideas what I might be doing wrong with the named export version? I kind of need to keep that structure for other parts of my app.

Thanks in advance!

You need to specify the named entrypoint in your Wrangler.toml.

K

kianOP•10/31/24, 2:41 AM

The name of the entrypoint to bind to. If you do not specify an entrypoint, the default export of the Worker will be used.

Those are probably shell commands. On macOS/Linux you run them in a Terminal, on Windows the easiest way is probably to use WSL https://learn.microsoft.com/en-us/windows/wsl/

also it really depends if your framework supports Pages or Workers. For remix, it looks like both: https://developers.cloudflare.com/workers/frameworks/framework-guides/remix/

Hi Will, in this page there is this "We plan to bridge the gaps between Workers and Pages and provide ways to migrate your Pages projects to Workers."

So I understand that the future will be workers in place of pages. Is my understand correct?

T

texan•10/31/24, 3:41 PM

We're seeing a lot more functionality from pages coming over to workers, but from what I'm hearing "pages is not going away"

I certainly think that you get more out of the box with workers, but to Chaika's point, assets in workers is still in beta

How does CF cname flattening work with CF proxying and workers?

If I flatten a cname will my worker never trigger because the response the DNS gives will cause the request to just skip cloudflares network?

Eelpupper so whats the latency like with KV or R2 with workers in the same region?

C

Chaika•10/31/24, 4:07 PM

R2 can be pretty quick, it's not the most consistent performance though. I think ~100ms or so uncached to R2, like EWR/ORD to ENAM bucket on average is around that. Just using workers binding and not cache.

If you use cache, either with r2 custom domain or cache binding, of course gets super quick, like under 40-50ms from all locations as long as you hit cache

KV is more complex. You don't have region control, the two central stores are always EU/US. Cached it's great, espec after recent perf changes, maybe knock off 10ms from what r2 cached would be. Uncached is more complex since no region control.

They both serve very different purposes though, KV is eventually consistent, infrequent updates, lots of writes, R2 is strongly consistent, more mixed usage

Worker Custom Domains or Routes?

C

Chaika•10/31/24, 4:07 PM

well -- you can't modify custom domains regardless afaik, and enabling flattening on proxied records wouldn't do anything

You will want to do the "incl passing existing bindings through" part though too!
